This is the logo for ANU debating. I had a little help for this; thanks to the un-named graphic designer(s) who created the original logo and identity, which gave me the colours, the 'ANU' (it's pretty much a customised Lucida Grande, which I've used for the 'debating') and the layout.

The illustration is mine; I tried to get it to reflect what most people think of when they think 'debating'. This is now used for all of the ANU Debating Society's official correspondence, in both colour and black.
This second one is part of an assignment - we were tasked with creating the identity for an independent Australian record label, of which I chose Spunk Records. This was a really hard one to do - their current logo is so good that it's hard to come up with something new and fresh that communicates the company.

In the end I settled on this design, using a base grid of triangles for letters. This grid was carried across to the whole identity, creating a series of geometric abstracts that could be used to tie the identity together.
